someone to type and print about 50 envelopes with addresses

I am looking for someone who can type and print about 50 custom designed envelopes with standard addresses. This is a one-time job and does not require any shipping or delivery; the envelopes will be picked up once they are printed. The necessary materials and supplies will be provided by the client and the freelancer will need to type the addresses into the envelopes and print them according to the client's specifications. This should not take more than a few hours to complete.
